5.3.2 Felling a tree or branch with TTC
The additional functionality, holding the branch in the position before cutting, can be used on the
moment the felling grapple has been placed around the tree or branch that should be removed.
Maneuver the grapple towards a tree or branch. Make sure that the felling grapple is able to position
itself without strain as it grabs hold. Now use the brake activation device and simultaneously all 3
brakes are activated. Both movements in the link and the tilt cylinder will be hold by the brakes.
Grapple grabs the branch and activating the brakes
As long as the operator activates the button of the brake activation device the brakes will be holding
the load in position. At all times the brake signal must be of a “make and hold” principle to ensure
that there is no unwanted activation of the brakes.
With the brakes still activated the tree or branch can now be moved to a position in which it can be
lowered.
